Final answer:
Suitable colors for building the pits on a compact disc, based on their wavelengths compared to pit dimensions, are violet, indigo, blue, and cyan. Green, yellow, orange, and red are unsuitable due to their longer wavelengths.
Explanation:
To determine which colors from the visible spectrum could be used for building the pits on a compact disc, we must consider the wavelength of light compared to the size of the pits. The pits on the disc measure 850 nm long by 500 nm wide. Visible light has wavelengths that range from approximately 400 nm for violet to 740 nm for red.
Based on this, colors that have a wavelength shorter than the size of the pits can be used to read the information. Using longer wavelengths would lead to diffraction and an inability to resolve the individual pits. Therefore, the suitable colors consist of violet, indigo, blue, and cyan, as their wavelengths are all shorter than or close to the dimensions of the pits. Green, yellow, orange, and red have wavelengths that are too long to be used effectively for this purpose.
It should be noted that CD technology specifically uses light with a wavelength of 780 nm, DVDs use 650 nm, and Blu-ray discs use 405 nm, indicating that different types of optical media require specific wavelengths of light based on the size of the pits and the spacing between them.
BI is an umbrella term that combines architectures, tools, databases, analytical tools, applications, and methodologies. b. BI is a content-free expression, so it means the same thing to all users. c. BI's major objective is to allow access to data (and models) to only IT. d. BI does not help transform data, to information (and knowledge), to decisions and finally to action.
Answer:
architectures, tools, databases, analytical tools, applications, and methodologies
Explanation:
There are several features of business intelligence. It is a content-free expression, which means that it means different things to different people, and not same thing as suggested by Option B. While its major objective is to enable or allow easy access to data, it is not limited to data and IT only as suggested by Option C. Instead it provides managers of businesses with the ability of analysis of data. And finally it helps in the transformation of data to information and to action, which is contrary to the suggestions of Option D. Hence the first option is the only correct option.
5)What are the differences in the function calls between the four member functions of the Shape class below?void Shape::member(Shape s1, Shape s2);void Shape::member(Shape *s1, Shape *s2);void Shape::member(Shape& s1, Shape& s2) const;void Shape::member(const Shape& s1, const Shape& s2);void Shape::member(const Shape& s1, const Shape& s2) const;
Answer:
void Shape :: member ( Shape s1, Shape s2 ) ; // pass by value
void Shape :: member ( Shape *s1, Shape *s2 ) ; // pass by pointer
void Shape :: member ( Shape& s1, Shape& s2 ) const ; // pass by reference
void Shape :: member ( const Shape& s1, const Shape& s2 ) ; // pass by const reference
void Shape :: member ( const Shape& s1, const Shape& s2 ) const ; // plus the function is const
Explanation:
void Shape :: member ( Shape s1, Shape s2 ) ; // pass by value
The s1 and s2 objects are passed by value as there is no * or & sign with them. If any change is made to s1 or s2 object, there will not be any change to the original object.
void Shape :: member ( Shape *s1, Shape *s2 ) ; // pass by pointer
The s1 and s2 objects are passed by pointer as there is a * sign and not & sign with them. If any change is made to s1 or s2 object, there will be a change to the original object.
void Shape :: member ( Shape& s1, Shape& s2 ) const ; // pass by reference
The s1 and s2 objects are passed by reference as there is a & sign and not * sign with them. If any change is made to s1 or s2 object.
void Shape :: member ( const Shape& s1, const Shape& s2 ) ; // pass by const reference
The s1 and s2 objects are passed by reference as there is a & sign and not * sign with them. The major change is the usage of const keyword here. Const keyword restricts us so we cannot make any change to s1 or s2 object.
void Shape :: member ( const Shape& s1, const Shape& s2 ) const ; // plus the function is const
The s1 and s2 objects are passed by reference as there is a & sign and not * sign with them. const keyword restricts us so we cannot make any change to s1 or s2 object as well as the Shape function itself.

In Programming Exercise 2, the class dateType was designed and implemented to keep track of a date, but it has very limited operations. Redefine the class dateType so that it can perform the following operations on a date, in addition to the operations already defined: a. Set the month. b. Set the day. c. Set the year. d. Return the month. e. Return the day. f. Return the year. g. Test whether the year is a leap year. h. Return the number of days in the month. For example, if the date is 3-12-2011, the number of days to be returned is 31 because there are 31 days in March. i. Return the number of days passed in the year. For example, if the date is 3-18-2011, the number of days passed in the year is 77. Note that the number of days returned also includes the current day. j. Return the number of days remaining in the year. For example, if the date is 3-18-2011, the number of days remaining in the year is 288. k. Calculate the new date by adding a fixed number of days to the date. For example, if the date is 3-18-2011 and the days to be added are 25, the new date is 4-12-2011.
Answer:
Java class is given below
Explanation:
class Date{
private int date;
private int month;
private int year;
public Date(){}
public Date(int date,int month, int year){
this.date= date;
this.month = month;
this.year = year;
}
public void setDate(int date){
this.date = date;
}
public void setMonth(int month){
this.month = month;
}
public void setYear(int year){
this.year = year;
}
public int getDate(){
return date;
}
public int getMonth(){
return month;
}
public int getYear(){
return year;
}
public boolean isLeap(int year){
return year%4==0
}
}
To redefine the dateType class and add the requested operations, modify the class and include methods like setMonth, setDay, setYear, getMonth, getDay, getYear, isLeapYear, daysInMonth, daysPassedInYear, daysRemainingInYear, and addDays.
Explanation:Redesigning the dateType ClassTo redefine the dateType class and add the requested operations, you can modify the existing class and include the following methods:
setMonth(int m): Set the month of the date.setDay(int d): Set the day of the date.setYear(int y): Set the year of the date.getMonth(): Return the month of the date.getDay(): Return the day of the date.getYear(): Return the year of the date.isLeapYear(): Test whether the year is a leap year.daysInMonth(): Return the number of days in the month.daysPassedInYear(): Return the number of days passed in the year.daysRemainingInYear(): Return the number of days remaining in the year.addDays(int numDays): Calculate the new date by adding a fixed number of days to the date.By implementing these methods, you can enhance the functionality of the dateType class to perform all the requested operations.

Explanation:
A 1 MB digital file needs to transmit a channel with bandwidth of 10 MHz and the SNR is 10 dB. What is the minimum amount of time required for the file to be completely transferred to the destination?
Answer:
A 1 MB digital file needs 0.23 seconds to transfer over a channel with bandwidth 10 MHz and SNR 10 dB.
Explanation:
We can calculate the channel capacity using Shannon's Capacity formula:
C = B + log₂ (1 + SNR)
Where C = Channel Capacity
B = Bandwidth of the Channel
SNR = Signal to Noise Ratio
We are given SNR in dB so we need to convert it into a ratio.
[tex]SNR_{dB}[/tex] = 10log₁₀ (SNR)
10 = 10log₁₀ (SNR)
1 = log₁₀ (SNR)
SNR = 10¹
SNR = 10
So, using Shannon Channel Capacity formula:
C = 10 x 10⁶ log₂ (1 + 10)
C = 34.5 MHz
Total amount of time required to transmit a 1MB file:
1MB = 1 x 8 Mbytes = 8Mb
C = 34.5 MHz = 34.5 Mb/s
Time required = 8Mb/34.5Mb/s = 0.23 seconds
A 1 MB digital file needs 0.23 seconds to transfer over a channel with bandwidth 10 MHz and SNR 10 dB.

Policies
RegulatoryAdvisoryInformativeSecurity policies
OrganizationalIssue-specificSystem-specificStandards
Actions or rulesSupportInternal or externalExplain why deploying software as a service can reduce the IT support costs for a company. What additional costs might arise if this deployment model is used?
Answer:
It reduces the cost of multiple subscription, but the cost of management is applied.
Explanation:
Cloud computing is the use of online resources like storage infrastructure available on database servers to hold company resources on a central level. There are various platforms available in adopting cloud services and they are SaaS or software as a service, PaaS, or platform as a service, IaaS or infrastructure as a service etc.
SaaS is a cloud computing services where software applications are made centrally available for an organisation. It reduces the cost of purchasing multiple activation keys for software traditionally installed. But it requires a skilled personnel and annual or monthly subscription, which when added together, might spike the cost of deployment.
Compare the elements of the basic Software Development Life Cycle with 2 other models. How are they similar? How are they different? Write a paragraph for each of 3 models describing each. Then write a paragraph comparing the differences and similarities among the 3. Your submission should be 1-2 pages of discussion.
Answer:
Explanation:
One of the basic notions of the software development process is SDLC models which stands for Software Development Life Cycle models. SDLC – is a continuous process, which starts from the moment, when it’s made a decision to launch the project, and it ends at the moment of its full remove from the exploitation. There is no one single SDLC model. They are divided into main groups, each with its features and weaknesses. The most used, popular and important SDLC models are given below:
1. Waterfall model
2. Iterative model
3. Spiral model
4. V-shaped model
5. Agile model
Stage 1. Planning and requirement analysis
Each software development life cycle model starts with the analysis, in which the stakeholders of the process discuss the requirements for the final product.
Stage 2. Designing project architecture
At the second phase of the software development life cycle, the developers are actually designing the architecture. All the different technical questions that may appear on this stage are discussed by all the stakeholders, including the customer.
Stage 3. Development and programming
After the requirements approved, the process goes to the next stage – actual development. Programmers start here with the source code writing while keeping in mind previously defined requirements. The programming by itself assumes four stages
• Algorithm development
• Source code writing
• Compilation
• Testing and debugging
Stage 4. Testing
The testing phase includes the debugging process. All the code flaws missed during the development are detected here, documented, and passed back to the developers to fix.
Stage 5. Deployment
When the program is finalized and has no critical issues – it is time to launch it for the end users.
SDLC MODELS
Waterfall – is a cascade SDLC model, in which development process looks like the flow, moving step by step through the phases of analysis, projecting, realization, testing, implementation, and support. This SDLC model includes gradual execution of every stage completely. This process is strictly documented and predefined with features expected to every phase of this software development life cycle model.
ADVANTAGES
Simple to use and understand
DISADVANTAGES
The software is ready only after the last stage is over
ADVANTAGES
Management simplicity thanks to its rigidity: every phase has a defined result and process review
DISADVANTAGES
High risks and uncertainty
Iterative SDLC Model
The Iterative SDLC model does not need the full list of requirements before the project starts. The development process may start with the requirements to the functional part, which can be expanded later.
ADVANTAGES
Some functions can be quickly be developed at the beginning of the development lifecycle
DISADVANTAGES
Iterative model requires more resources than the waterfall model
The paralleled development can be applied Constant management is required
Spiral SDLC Model
Spiral model – is SDLC model, which combines architecture and prototyping by stages. It is a combination of the Iterative and Waterfall SDLC models with the significant accent on the risk analysis.
In C#Write the program SubscriptExceptionTest in which you use an array of 10 doubles. Write a try block in which you place a loop that prompts the user for a subscript value and displays the value stored in the corresponding array position or asks the user to quit the program by entering 99. Create a catch block that catches any IndexOutOfRangeException and displays the message: Index was outside the bounds of the array.
Answer:
using System;
namespace ConsoleApp3
{
class Program
{
static void Main(string[] args)
{
double[] doubleArray = { 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0 };
Console.WriteLine("Double Array values are:");
foreach (var b in doubleArray)
{
Console.WriteLine(b);
}
Console.WriteLine("Enter value to find position in Array");
var input = Console.ReadLine();
var value = Convert.ToDouble(input);
if (value == 99.0)
{
Environment.Exit(0);
}
try
{
var index = Array.IndexOf(doubleArray, value);
if (index == -1)
{
Console.WriteLine("Index was outside the bounds of the array");
Console.ReadLine();
}
else
{
Console.WriteLine("Position in Array is:" + index);
Console.ReadLine();
}
}
catch (Exception e)
{
Console.WriteLine("Index was outside the bounds of the array");
Console.ReadLine();
}
}
}
}
Explanation:
this is the code of console program which initialize the double array from 1-10 and displays the existing values of array in console.
Then it will take input from user, convert it to double and find the value position in double array.
if 99, then program will be exist
if exist in array:display the index position
else:index was outside the bounds of the array in try catch block.
Write a Python function uniquely_sorted() that takes a list as a parameter, and returns the unique values in sorted order.

Call the predefined function sort(for sorting). Finally, call the function uniquely_sorted() inside the print function.
In a point-to-point single network, how many physical links will there be when a packet is transmitted?
Answer:
One
Explanation:
A network is the interconnection and communication of two or more computer devices. Computer systems on a network shares resources with one another, using network standards like OSI and TCP/IP suite model and using the protocols on each layers.
There are two major types of network communication between devices and they are peer to peer or point to point Network and client-server network.
Point to point Network uses one secure physical link to connect two computers or routers in a network.
Write a function solution that returns an arbitrary integer which is greater than n.
Answer:
public static int greaterThanInt(int n){
return n+10;
}
Explanation:
This is a very simple method in Java. it will accept an argument which is an integer n and return n+10 since the question requires that an arbitrary integer greater than n be returned adding any int value to n will make it greater than n.
A complete java program calling the method is given below:
import java.util.Scanner;
public class ANot {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Please enter an integer");
int n = in.nextInt();
int greaterInt = greaterThanInt(n);
System.out.println("You entered "+n+", "+greaterInt+" is larger than it");
}
public static int greaterThanInt(int n){
return n+10;
}
}

Lossless and lossy are the two (2) universally known categories of compression algorithms. Compare the two (2) categories of algorithms, and determine the major advantages and disadvantages of each. Provide one (1) example of a type of data for which each is best suited.
Answer:
The lossy compression method is also known as irreversible compression and is beneficial if the quality of the data is not your priority. It slightly degrades the quality of the file or data but is convenient when one wants to send or store the data. This type of data compression is used for organic data like audio signals and images. The algorithm use in Lossy compression include: Transform coding, DCT, DWT, fractal compression, RSSMS.
The Lossless compression method is also known as reversible compression and is capable of reconstituting the original form of the data. The quality of the data is not compromised. This technique allows a file to restore its original form. Lossless compression can be applied to any file format can improve the performance of the compression ratio. The algorithm use in Lossless compression include: RLW, LZW, Arithmetic encoding, Huffman encoding, Shannon Fano coding.
Advantage of Lossy compression: Lossy compression can achieve a high level of data compression when compared to lossless compression.
Advantage of Lossless compression: Lossless compression doesn’t degrade the quality of data during compression
Disadvantage of Lossy compression: Lossy compression degrades the quality of the data during compression
Disadvantage of Lossless compression: Lossless compression has less data holding capacity when compared to lossy method
Example of type of data for Lossless compression: Text
Example of type of data for Lossy compression: Audio
Explanation:
Answer:
Lossless retains the file size while lossy algorithm discards excess files size or parts.
Explanation:
Compression algorithms are algorithms used to minimise the file size of a large file format. It is handy for maximising available disk space and reduce upload and download time of these files. Lossless and lossy are two types of compression algorithms.
Lossless algorithm is used to compress a file, but yet retains the structure of the original file or data. It is used where an identical file from the original is favourable and is used in archives.
Lossy is the opposite of lossless because it discards excess parts of a file. It is used in compressing audio files like MP3.

Answer:
Answer explained below. The remaining part of the question is incomplete
Explanation:
The concepts of confidentiality, integrity, and availability (C-I-A) can be explained in following given points.
1) Confidentiality: Its basically refer to the confidentiality of the information. Here we can think about the protection of the information from unauthorized person. Confidentiality enuser that at what level your information is secured and no unauthorized access will be done to the information. For maintaining the confidentiality, we can use various encryption methods. The main concept of confidentiality is to enforce various techniques like encryption, file permissions and access control to restrict access to important information.
2) Integrity: Integrity of the information refer to the unwanted modification of the information. Integrity of the data as well as the information should be maintained and only the autorized person can access as well as modify the information. For enforcing the integrity, we can implement various hashing techniques on information.
3) Availability: Availability refers to the availability of the information, when ever an autorized person requests for the information. High availability of the information should occur, so that any autorized person can access it, when ever its required. For high availability, we can create backup as well as replicate the data across the geo sites.
Seven domains of a typical IT infrastructure are given below:
1) User Domain: Its refer to the group of users as well as the person who access the information systems.
2) LAN Domain: Refer to the local area network, where various computers are connected to each other.
3) Workstation Domain: The area is called workstation, where various users connect to the IT infrastructure.
4) WAN and LAN link domain: Refer to the connection of local area network to wide area network.
5) WAN domain: Refer to the wide area network, connection of computers in large area.
6) Storage Domain: Refer to the storage, where we store the data.
7) Remote Access Domain: Refer to the domain where mobile user can access the local as well as wide network remotely.

Calculate the number of hours since the birthdate. Insert your calculation in cell C15. (hint: convert the number of days to number of hours by multiplying the number of days in C14 by 24.)
Final answer:
To calculate the number of hours since a birthdate, multiply the number of days by 24 and insert the result in cell C15.
Explanation:
To calculate the number of hours since the birthdate, you need to first determine the number of days that have passed since that date. Once you have the number of days in cell C14, you multiply it by 24 to convert the number of days to a number of hours. For example, if cell C14 contains 10 days, then you would calculate the hours as follows:
10 days x 24 hours/day = 240 hoursYou would then insert the result, 240 hours, into cell C15 to complete the calculation.
The number of hours since the birthdate is calculated by multiplying the number of days in cell C14 by 24.
ExplanationTo determine the duration in hours since the birthdate, the process involves converting the number of days provided in cell C14 into hours. As there are 24 hours in a day, multiplying the number of days by 24 yields the total number of hours.
This formulaic approach accounts for the full span of days indicated, translating it accurately into an hourly representation.
Act on converting different time units to facilitate precise calculations for varied temporal requirements. Understanding these conversions aids in transforming durations to the most fitting unit, catering to specific contexts and calculations.
1.) You are a digital forensic examiner and have been asked to examine a hard drive for potential evidence. Give examples of how the hard drive (or the data on it) could be used as (or lead to the presentation of) all four types of evidence in court; testimonial, real, documentary, and demonstrative. If you do not believe one or more of the types of evidence would be included, explain why not.
Answer & Explanation:
The hard drive could contain some type of reports which might prove to be the evidence of some bad guys involved. Some real evidence such as images or documents related to the crime committed such as corruption-related property papers details of bank accounts along with a possibility that it may also contain a video recording which may prove as evidence. so there shouldn't be any demonstrative proof which can present there by having a hard drive and can be used as evidence in the court.
1. Write an expression whose value is the result of converting the str value associated with s to an int value. So if s were associated with "41" then the resulting int would be 41.2. Write an expression whose value is the last character in the str associated with s.
3. Given variables first and last, each of which is associated with a str, representing a first and a last name, respectively. Write an expression whose value is a str that is a full name of the form "Last, First". So, if first were associated with "alan" and last with "turing", then your expression would be "Turing,Alan". (Note the capitalization! Note: no spaces!) And if first and last were "Florean" and "fortescue" respectively, then your expression’s value would be "Fortescue,Florean".
4. Write an expression whose value is the result of converting the int value associated with x to a str. So if 582 was the int associated with x you would be converting it to the str "582".

Why are user application configuration files saved in the user’s home directory and not under /etc with all the other system-wide configuration files? ____________________________________________________________________________________
Explanation:
The main reason why is because regular users don't have permission to write to /etc. Assuming this is Linux, it is a multi-user operating system. Meaning if there are user-application configuration files within /etc, it would prevent users from being able to customize their applications.
The top 3 most popular male names of 2017 are Oliver, Declan, and Henry according to babynames.
1. Write a program that modifies the male_names set by removing a name and adding a different name. Sample output with inputs: 'Oliver' 'Atlas' { 'Atlas', 'Declan', 'Henry' }
NOTE: Because sets are unordered, the order in which the names in male_names appear may differ from above.
male_names = {'Atlas', 'Declan', 'Henry'}
def modify_names(old_name, new_name, names_set):
names_set.discard(old_name)
names_set.add(new_name)
return names_set
male_names = {'Oliver', 'Declan', 'Henry'}
old_name = input("Enter the name to remove: ")
new_name = input("Enter the name to add: ")
new_male_names = modify_names(old_name, new_name, male_names)
print(new_male_names)
Enter the name to remove: Oliver
Enter the name to add: Atlas

Write a function so that the main program below can be replaced by the simpler code that calls function mph_and_minutes_to_miles(). Original main program:miles_per_hour = float(input())minutes_traveled = float(input())hours_traveled = minutes_traveled / 60.0miles_traveled = hours_traveled * miles_per_hourprint('Miles: %f' % miles_traveled)Sample output with inputs: 70.0 100.0Miles: 116.666667
Final answer:
To replace the original main program with a function, define the function mph_and_minutes_to_miles() that prompts the user to enter miles per hour and minutes traveled, calculates the miles traveled, and displays the result.
Explanation:
To replace the original main program with the function mph_and_minutes_to_miles(), you can define the function as follows:
def mph_and_minutes_to_miles():Then, you can simply call the mph_and_minutes_to_miles() function in your main program:
mph_and_minutes_to_miles()This will prompt the user to enter the miles per hour and minutes traveled, and then calculate and display the miles traveled.
Final answer:
To simplify the main program, define a function called mph_and_minutes_to_miles() that takes two inputs: miles_per_hour and minutes_traveled. Inside the function, calculate the hours_traveled by dividing minutes_traveled by 60.0. Then, calculate the miles_traveled by multiplying hours_traveled by miles_per_hour. Finally, print the result using the format() function.
